GREASE-9UP- Application filed May 22, law.

T all vkom t may con e Be 1t kno n that I, Arrrrn T QMEY, a

citizen of the United States,and a resident of Edrnore, in the county ofRamsey and State o orth Dakota, v inv nt d. a cer ain ew n usef l I pr vment in Grease-Cups, of which the following is a pe ifi ation.

This inv ntion r ates t an i p ov ment in grease cups.

One of the principal objects of the invention is to provide an improvedgrease cup having a cap hingedly connected to the body of the cup andcarrying the plunger and associated mechanism, whereby the cup may bereadily opened for filling, by simply swinging the cap back upon itshinges and without the necessity of the removal of any of the parts.

Another object of the nvent n is to pr vide an improved grease cuphaving or top to which a screw driven plunger is connected forreciprocation within the body of the cup, means being hingedlyconnected. to the cup for preventing the rotation of the plunger withthe screw.

A still further object of the invention is to provide an improved greasecup of the class described, which will be extremely simple, durable,eflicient in operation, and inexpensive to manufacture,

With these and other objects in View which will become apparent as thedescription proceeds, the invention resides in the construction,combination, and arrangement of parts hereinafter more fully describedand claimed and illustrated in the accompanying drawings in which likecharacters of reference indicate like parts throughout the severalfigures, of which- Figure 1 represents a view in section takenvertically and centrally through a grease cup constructed according tomy invention. Fig. 2 represents a view in section taken horizontally onthe plane indicated by the line 2-2 of Fig. 1, looking in the directionindicated by the arrow. Fig. 3 represents a top plan view of the cup.

In carrying out my invention, I provide a cup whose body is indicated at5. The body as shown, is substantially cylindrical and is provided withan inclined floor 6 merging centrally into an exteriorly screw threadedhollow stem 7 adapted to be connected with the part to be lubricatedwheresp iiq t en of w en, P ent- V Patented Nov, 9;, 1915.

by to dispose the grease cup in proper posit on.

A dome-shaped cap or cover 8 is hingedly onn cte as t 9 with the body 5-The up he? edge of h s b dy s beve ed nw y and the lower edge of the cap8 is correspondingly beveled whereby as clearly indi' cated in Fig. 1,whenthe cap is in'closed position upon the body an extremely tight Jointbetween the edges of the body and cap is provided as indicated at 10,.At a point iametrical y opp se to he p in at which hinge 9 is connectedwith cap 8 a resilient 9 1F 11 0r 11 is connected to said cap, the lowerend of which depends below the lower edge of the cap. A pin 12 carriedupon the body 5 is adapted to be engaged by the r 1 h gh n op ning i hlatter, whereby to maintain the cap in closed position upon the bodyportion at will.

Disposed within cap 8 and swiveled near its upper end at the apex of thecap, is a threaded bolt or screw 13. The later extends within the capand when said cap is elosed position upon the body of the grease cup,lies in the axis of the latter. Secured in suitable manner to the upperend of screw 13 on the outside of cap 8, is a turn button ll. The edgesof the latter are serruee ed o s al p d s a while he central portion 16is of a concavo-con-vex formation whereby to snugly rest upon the outersurface of the cap. By actuating this turn button l t, the screw 13 maybe turned in one direction oranother at will.

T Pl n e h ugh t p io which suitable pressure is adapted to be exer-tedupon the contents of the cup at will, includes the upper and lowerplates 17, between which a leather or other suitable washer 18 is bound,the edges of said washer being stamped over to provide a packing for theplunger. This plunger is of a diameter substantially equal to orslightly less than the internal diameter of body 5. The plunger iscarried upon the lower end of a squared shank 19, having a threadedlongitudinal bore through which the screw 13 is turned.

In order that the shank 19 may be held against rotation with thescrew'13 while the latter is turned in reciprocating the plunger withinthe grease cup, a substantially rectangular guide loop 20 is provided.This loop at one end is hingedly connected through the medium of a clip21, with the cap 8 inside of the latter, and at a distance above thelower edge of said cap. The

loop is adapted to swing upon its hinged end upwardly and downwardly.The stem 19 extends through the loop as clearly indicated in Fig. 2, andthe loop is of such length that no matter whether the stem or shank 19be at the upper or lower extremity of its movement, it will be embracedon two sides by the side bars of the loop. This guide 100p rests at itsouter end upon the plunger through the action of gravity. The length ofthe shank 19 is such that the plunger may be forced clear into the lowerend of the grease cup in order to entirely empty the same. I

Such a grease cup as I have provided may readily be opened by simplydisengaging the arm 11 from pin 12 and swinging the cap back upon itshinge 9, so that no disadvantages incident to the ordinary grease cup,through the operation of removing various parts of the cup, areexperienced. Before swinging the cap into open position, the plungerwill be withdrawn into the cap so as to be in position when the cup isfilled with grease, to be moved into the upper end of the cup whereby toexert the desired pressure upon the contents thereof. All of theoperative parts of the device are carried by the cap, so that anextremely compact and simple construction and arrangement of parts isthus provided.

Although I have described the preferred embodiment of my invention, Imay desire to make such changes in the construction, combination, andarrangement of parts thereof, as do not depart from the spirit of theinvention and the scope of the appended claims.

I claim r 1. A grease-cup comprising a cylindrical body, a dome-shapedcap hingedly connected therewith, means for detachably connectingthe'cap and body' together in closed position, a screw swivellyconnected with the cap and disposed within the same, a turn buttonfixedly connected with the screw and arranged exteriorly of the cap, asquared shank through which said screw is threaded, a plunger carried bythe shank, and a rectangular loop hingedly connected adjacent one endwith the cap and through which loop said shank extends, said loopadapted to maintain the shank against rotation.

2. A grease cup comprising a cylindrical body, a dome-shaped caphingedly connected therewith, a screw swivelly connected with the capand extending within the same, means whereby the screw may be operatedat will from without the cap, a shank threaded upon the screw and beingprovided with a plunger, and means hingedly connected with the capwithin the latter and engaging the shank for preventingrotation of thelatter.

3. A grease-cup comprising a body, a cap hingedly connected therewith, aplunger connected with the cap and adapted to be reciprocated at willwithin the body, and means carried by the cap for preventing rotation ofthe plunger under influence of its operating means.

i. A grease-cup including a body, a cap hingedly connected therewith, ascrew carried by the cap and adapted to be rotated at will, a plungermounted upon the screw, and means carried by the cap for preventingrotation of the plunger when the screw is turned.

5. In a grease cup, a body, a cap hingedly connected therewith, aplunger mechanism carried by the cap, and a loop hingedly connected tothe cap and operably engaging the plunger mechanism for limiting thelatter to a reciprocating movement.
